Feuerung mit Rauchverzehrung durch eine Nebenfeuerung.Firing with smoke consumption through a secondary firing.

Patentiert im Deutschen Reiche vom 8. September 1905 ab.Patented in the German Empire on September 8, 1905.

Die Erfindung betrifft eine Feuerung mit Rauchverzehrung durch eine Nebenfeuerung, und es kommt dabei in erster Linie darauf an, daß die Nebenfeuerung in einer Rauchverzehrungskammer von kreisförmigem Querschnitt sich befindet, welche hinter der Feuerbrücke angeordnet ist. In dieser Rauchverzehrungskammer werden die Rauchgase in an sich bekannter Weise durchThe invention relates to a furnace with smoke consumption by a secondary furnace, and it is primarily important that the secondary firing is in a smoke consumption chamber is of circular cross-section, which is located behind the fire bridge. In this Smoke consumption chamber are the smoke gases in a known manner

ίο schiefwinklig eingeführte Luftströme in kreisende Bewegung versetzt. Die Annahme dieser kreisenden Bewegung durch die Rauchgase wird durch die schiefwinklige Anordnung der Brenner in jener Rauchverzehrungskammer unterstützt. Infolge der kreisenden Bewegung kommen die Rauchgase in innige Berührung mit den Flammen der Brenner, und der Rauch wird auf diese Weise vollständig verzehrt. Dadurch, daß man der Verbrennungskammer die Gestalt eines nach oben sich verjüngenden abgestumpften, oben offenen Hohlkegels gibt, wird dafür gesorgt, daß die Gase längere Zeit in der Verbrennungskammer verweilen und in dieser kreisen.ίο Air streams introduced at an oblique angle in circling Movement. The acceptance of this circular motion by the smoke gases is due to the oblique arrangement of the burners in that smoke consumption chamber supports. As a result of the circular movement, the flue gases come into close contact with the flames of the burner, and the smoke is completely consumed in this way. By being the Combustion chamber the shape of an upwardly tapering truncated, above open hollow cone, it is ensured that the gases in the combustion chamber for a longer time linger and circle in this.

Um die über die Feuerbrücke tretenden Rauchgase in die Verbrennungskammer hineinzuleiten, wird die Rückwand der Feuerbrücke halbkreisförmig ausgehöhlt und nach der Rauchverbrennungskammer zu abgeschrägt. Außerdem wird zu dem gleichen Zwecke über der Verbrennungskammer ein vom Heizerstand aus zu bewegender Schieber angeordnet, durch welchen den Rauchgasen der Weg unter dem Kessel und über die Rauchverzehrungskammer hinweg verlegt werden kann, so daß¹ diese gezwungen sind, in die Rauchverzehrungskammer einzutreten.In order to guide the smoke gases passing over the fire bridge into the combustion chamber, the rear wall of the fire bridge is hollowed out in a semicircle and beveled towards the smoke combustion chamber. In addition, arranged for the same purpose on the combustion chamber from the heater booth to moving slide, may be through which the flue gases of the way under the boiler and the Rauchverzehrungskammer moved away, so that ^1, these are forced to enter the Rauchverzehrungskammer.

Die Erfindung ist an einer Dampfkesselfeuerung ι von bekannter Form erläutert, welche mit einem in dem Mauerwerk 3 gelagerten zylindrischen Kessel 2 mit Heizröhren 4, Kammer 5 und Abzug 6 versehen ist. Die Feuerbrücke 11, welche hinter der Verbrennungskammer 10 mit ihrem Rost 8 und Aschenfall 9 liegt, ist am oberen Rande 12 halbkreisförmig gekrümmt (s. Fig. 2).The invention is explained on a steam boiler ι of known form, which with a mounted in the masonry 3 cylindrical boiler 2 with heating tubes 4, chamber 5 and trigger 6 is provided. The fire bridge 11, which behind the Combustion chamber 10 with its grate 8 and ash trap 9 is on the upper edge 12 semicircular curved (see Fig. 2).

Hinter dem Feuerraum 10 und unter dem rückwärtigen Teil des Kessels 2 ist eine Hilfsverbrennungskammer 15 von kreisförmigem Querschnitt und der Gestalt eines abgestumpften Kegels vorgesehen. Zu diesem Zwecke sind die Steine 16 der Kammerwandung radial angeordnet (s. Fig. 5) und es ragt immer die nächste höhere Steinreihe ein wenig nach dem Innern der Kammer hin über die darunterliegende Steinreihe hinaus (s. Fig. 2 und 3). Die Steine 16 sind nur an ihren inneren Enden mittels feuerfesten Tons 17 miteinander verbunden, während außen Zwischenräume 18 zwischen ihnen frei-Behind the furnace 10 and under the rear part of the boiler 2 is one Auxiliary combustion chamber 15 of circular Cross-section and the shape of a truncated cone provided. For this purpose, the stones 16 are the chamber wall arranged radially (see Fig. 5) and the next higher row of stones always protrudes a little towards the interior of the chamber beyond the row of stones below (see Figs. 2 and 3). The stones 16 are only refractory at their inner ends Tons 17 connected to one another, while outside spaces 18 between them free-

left to allow expansion and contraction. In the chamber 15 burners 19 are arranged at an oblique angle to the chamber wall, the flames of which set the flue gases in the chamber in circular motion. The burner tubes 19 are inserted into the chamber through channels 20 which are provided in the masonry 3, so that during the circular movement of the gases in the chamber 15, air is sucked into them through those channels 20 which supports the complete combustion of the flue gases .
A hollow partition 21 is provided across the auxiliary combustion chamber 15, in which a slide 22 is arranged. This partition consists of two parts 23 and 24, between which the slide 22 slides and which rest on a base 25 made of refractory clay. This beam-like support extends across the middle of the upper part of the chamber 15. The front part 23 of the partition ends at some distance from the bottom of the boiler so that the heated air and the combustion products can pass directly under the boiler when the slide 22 is lowered.

The slide 22 consists of a refractory clay plate 26, the upper end of which is approximately is cut out in a semicircle so that it fits closely to the when raised Can create the bottom of the boiler 2 (see. Fig. 2 and 3). The lateral ends 27 of this clay plate slide in. vertical slots or channels 28 which are formed in the masonry 3. The plate 26 is on a Casting 29 attached with pin 30, which sits at the upper end of a rod 31,

which protrudes through an opening 32 of the carrier 25 and through the tubular support 33. At the lower end of the rod 31, which is in one under the bottom of the furnace located chamber 34 protrudes, a grooved roller 35 is provided, which on demeinen Arm of a lever 36 (Fig. 3) rests. This lever 36 is rotatable at 37 on the support 38 attached. His other arm is engaged with a similar grooved roller 39, the at the lower tapered end 40 a serving as a counterweight for the slide 22 Piston 41 is arranged. This piston slides in the airtight cylinder 42, which is fastened to the outside of the masonry 3 by means of holders 43. Of the Cylinder 42 is provided at its upper end with a three-way cock 44 through which Compressed air or another suitable drive means for moving the piston 41 can be in and out. The valve 44, which is of any construction, can Either automatically or by hand can be conveniently operated from the heater stand. The cylinder 42 is capped at its upper end by a threaded cap 45 closed with a gland 47 and a gland 46 at its lower end. Releases air, steam, or other propellant through valve 44 into the top of the cylinder 42, so the piston 31 is lowered and the slide 22 lifted into the closed position shown in FIG. 3, while on the other hand when the air or steam escapes, the slider moves as a result of its own weight will lower out of the cylinder. The through the lever linkage 46 ', 48, 49, 50, 51, 52 connected to the piston 41 flap 7 of the chimney 6 opens and closes in on in a known manner inevitably to move the slide 22.

To safely pass the combustion products through the inlet port 55 in The rear wall 57 of the fire bridge 11 is to lead in the smoke combustion chamber Hollowed out in a semicircle and sloping towards the smoke combustion chamber (see Fig. 4). If the smoke gases pass over the hollowed surface of the bridge 11, so they bump against the slide 22 and the partition wall 21, bounce against the beveled semicircular rear wall 57 of the bridge 11 back and are along this passed through the opening 55 into the combustion chamber 15. After this The gases then have circled in that chamber, the smoke being released by the touch will have been consumed with the flames of the burner 19, they will get through the outlet opening 56 of that chamber into a second between the rear side 24 of the Separating wall 21 and a baffle wall 59 formed and provided with burners 61 chamber 58. From the chamber 58 strike the Combustion gases back around the end of the boiler through the heating tubes 4 and out through the chimney 6. During the period during which little or no unburned If components get over the fire bridge, the slide 22 can be lowered and the flap 7 closed, whereupon the combustion gases immediately below the boiler and above the partition wall 21 can stroke.
